Matcha belongs to the green tea family, but it's used as a concentrated powder instead of dried leaves. This makes matcha higher in caffeine and an amino acid called L-theanine, a compound linked to feelings of focus, alertness, and sustained energy. Sometimes the benefits of matcha get conflated with weight-loss claims, so a word to the wise: The only real way matcha will help you lose weight is by drinking it in place of soda, juice, and energy drinks. Sugar-sweetened drinks are the #1 source of added calories in the American diet, so plain matcha is a smart swap.
